Narrative:
After being cleared for takeoff; pilot flying added takeoff thrust. Pilot monitoring set thrust. At approximately 20 knots engine takeoff message occurred. Rejected takeoff was accomplished. ATC was immediately notified and request was made to exit runway with no assistance needed. After exiting runway; request was made to troubleshoot issue. ATC cleared aircraft to park on taxiway in order to confirm all takeoff numbers were correct. Flight attendants and passengers were notified of the issue and told to remain seated with their seatbelts fastened. Maintenance was contacted. Maintenance provided that all parameters appeared normal and that auto throttles did not arm properly. Maintenance cleared pilots to attempt another takeoff as no other issues or incorrect parameters were noted. Maintenance found no reason to have aircraft return to gate for inspection.upon receiving clearance from ATC to taxi to runway; clearance for takeoff was once again received from ATC. No further issues occurred on takeoff. Auto throttles did not arm or were inadvertently deselected prior to adding takeoff thrust. After selecting a/T verify to is armed on pfd before adding thrust. After thrust is added; upon checking thrust; visually verify to has armed properly.
